Bronchiectasis - How ya feeling?

Hi - I'm 64 years with and have had Bronch for 14 years. It's considered "advanced" now. I have had pretty much every bacteria and fungus throughout this time including MAC. Right now, for the first time in a long time, My sputum samples are good, I am not on any meds except my daily AC. I am otherwise healthy. My problem is I have daily fatigue, breathlessness and still cough up a lot of sputum (like a cup a day) as well as daily cough. But I otherwise feel well. I'm trying to determine if this is my baseline. In other words, are my symptoms from the lung damage so bad that I won't get any better? Does anyone have similar problems who have the condition without being in an exacerbation? My Pulm says it's hard to tell how I feel and says to do my best to push through to exercise my lungs (which I do). Any input would be appreciated. Thank you!
